@umakantp/react-date-range

A date library agnostic React component for choosing dates and date ranges. Uses date-fns for date operations.

Notice

This project is forked from hypeserver/react-date-range, which was unmaintained because the original maintainers are busy with other things. I forked this for my own use. In case it helps anyone, I'm keeping it here open for all. The sponsors link above goes to the original authors since they spent 99% of their time on this code.

The types are taken from https://github.com/DefinitelyTyped/DefinitelyTyped/tree/master/types/react-date-range which I believe is community sourced or may be original authors created them.

Versions

2.0.0 version was more of experimental, have errors and typescript types missing. Refer to version 2.1.0 onwards

Why should you use @umakantp/react-date-range?

• Stateless date operations
• Highly configurable
• Multiple range selection
• Based on native js dates
• Drag n Drop selection
• Keyboard friendly

Getting Started

Installation

npm install --save @umakantp/react-date-range

This plugin expects react and date-fns as peerDependencies, It means that you need to install them in your project folder.

npm install --save react date-fns

Usage

You need to import skeleton and theme styles first.

import '@umakantp/react-date-range/dist/styles.css'; // main style file
import '@umakantp/react-date-range/dist/theme/default.css'; // theme css file

DatePicker

import { Calendar } from '@umakantp/react-date-range';

function App() {
  const handleSelect(date) {
    console.log(date); // native Date object
  }

  return (
    <div>
      <Calendar
        date={new Date()}
        onChange={handleSelect}
      />
    </div>
  );
}

DateRangePicker / DateRange

import { DateRangePicker } from '@umakantp/react-date-range';

function App() {
  const handleSelect = (ranges) => {
    console.log(ranges);
    // {
    //   selection: {
    //     startDate: [native Date Object],
    //     endDate: [native Date Object],
    //   }
    // }
  };

  const selectionRange = {
    startDate: new Date(),
    endDate: new Date(),
    key: 'selection'
  };

  return (
    <DateRangePicker
      ranges={[selectionRange]}
      onChange={handleSelect}
    />
  );
}

*shape of range:

 {
   startDate: PropTypes.object,
   endDate: PropTypes.object,
   color: PropTypes.string,
   key: PropTypes.string,
   autoFocus: PropTypes.bool,
   disabled: PropTypes.bool,
   showDateDisplay: PropTypes.bool,
 }

**shape of ariaLabels:

 {
   // The key of dateInput should be same as key in range.
   dateInput: PropTypes.objectOf(
     PropTypes.shape({
       startDate: PropTypes.string,
       endDate: PropTypes.string
     })
   ),
   monthPicker: PropTypes.string,
   yearPicker: PropTypes.string,
   prevButton: PropTypes.string,
   nextButton: PropTypes.string,
 }

Infinite Scrolled Mode

To enable infinite scroll set scroll={{enabled: true}} basically. Infinite scroll feature is affected by direction(rendering direction for months) and months(for rendered months count) props directly. If you prefer, you can overwrite calendar sizes with calendarWidth/calendarHeight or each month's height/width with monthWidth/monthHeight/longMonthHeight at scroll prop.

  // shape of scroll prop
  scroll: {
    enabled: PropTypes.bool,
    monthHeight: PropTypes.number,
    longMonthHeight: PropTypes.number, // some months has 1 more row than others
    monthWidth: PropTypes.number, // just used when direction="horizontal"
    calendarWidth: PropTypes.number, // defaults monthWidth * months
    calendarHeight: PropTypes.number, // defaults monthHeight * months
  }),

Release workflow

• Merge everything that needs to be in the release to master
• Open a new release PR than:
  • bumps version to appropriate one <new_version>
  • Update CHANGELOG.md
• Make sure the demo and important features are working as expected
• After merging, tag the master commit with release/<new_version> and let Github Action handle publishing
• = Win 🙈

TODOs

• Make mobile friendly (integrate tap and swipe actions)
• Add tests
• Improve documentation
